During a run of rsync of /etc/master.passwd my 2.2.7-RELEASE
server panic'd. Any help in this would be really appreciated. In my
limited kgdb skills, it trap()'d in ufs_rename() with the inodes the
same. This is a production server so I am a little worried.
Is this a known issue of *any* sort?
Or, is there something more I can do with my core/kernel and
gdb to help diagnose an unknown issue?
(Appended are a backtrace, dmesg, and kernel conf)
Thanks,
-Kevin
